Negation, Coordination, and Quantifiers in Contextualized Language Models (2022.coling-1)
Copied to clipboard
| Challenge: | Recent work has focused on specific tasks and on the learning outcome. |
| Approach: | They propose to decouple the weaknesses from specific tasks and focus on the embeddings per se and their mode of learning. |
| Outcome: | The proposed model can learn semantic constraints and how the context impacts their embeddings. |
Explaining Contextualization in Language Models using Visual Analytics (2021.acl-long)
Copied to clipboard
| Challenge: | Contextualized language models (LMs) have learned highly transferable and task-agnostic properties of language, even to a degree of imitating the classical NLP pipeline. |
| Approach: | They propose to use an existing similarity-based score to measure contextualization and integrate it into a visual analytics technique that combines the model's layers simultaneously and highlighting intra-layer properties and inter-layer differences. |
| Outcome: | The proposed approach combines linguistically-informed insights with scoring and visual analytics to show that contextualization is neither driven by polysemy nor by pure context variation. |
